Abstract: An electromagnetic relay includes a fixed terminal, a movable contact piece, a first contact, and a second contact. The fixed terminal includes a first surface. The movable contact piece includes a second surface disposed to face the first surface. The first contact is embedded in one of the fixed terminal or the movable contact piece to be flush with one of the first surface or the second surface. The second contact is disposed on the other of the fixed terminal or the movable contact piece to face the first contact. The second contact protrudes from the other of the first surface or the second surface toward the first contact and include a contact surface smaller than the first contact when viewed from a direction facing the first contact.

Abstract: The electromagnetic relay includes a fixed terminal, a fixed contact connected to the fixed terminal, a movable contact piece moving in an opening direction and a closing direction with respect to the fixed terminal, a movable contact connected to the movable contact piece and being arranged to face the fixed contact, a coil generating an electromagnetic force to move the movable contact piece, and a drive circuit controlling a current to the coil. The drive circuit increases the current at a first increase rate in a first period that includes a period from a start time when the current starts to flow in the coil to before a contact time point at which the movable contact contacts the fixed contact. The drive circuit increases the current at a second increase rate larger than the first increase rate in the second period that includes a period after the contact time point.

Abstract: A relay includes a movable contact piece having a movable contact, a fixed contact, a drive device configured to move the movable contact piece, a magnet to apply a Lorentz force to an arc in a first extension direction, a fixed terminal having an intermediate portion to apply a Lorentz force to the arc in a second extension direction, and a wall portion. The wall portion includes first and second wall surfaces. The first wall surface is disposed to face an arc-extinguishing space, and is disposed opposite to the movable contact and the fixed contact in the first extension direction. The second wall surface is disposed to face the arc-extinguishing space and is disposed downstream in the second extension direction with respect to the first wall surface. A distance from the movable contact piece to the second wall surface differs from a distance to the first wall surface.

Abstract: To immediately reflect replacement of a field device in a network, a field device is provided. When a field device is newly connected to a low-order network due to replacement or the like, a state in which there is no connection changes to a state in which a connection portion has connected to the network and the change is detected by a connection detecting portion. This causes an address information transmitting portion to transmit an IP address and a MAC address stored in a network information storing portion to the low-order network and they reach a router. In the router, a table containing correspondence between set MAC addresses and IP addresses is updated based on the new information.
